  • Porous pulp molding dies have been made of a woven wire cloth material, which is stretched to conform to a die surface. Such dies have some disadvantages in terms of the amount of distortion or stretching of which the wire cloth is capable to enable it to conform to the die surface. Further disadvantages include the propensity of the wire cloth to rupture.
  • the use of wire cloth is also associated with some limitations on the complexity of the products that can be molded. In particular, when forming a wire cloth into a mold, the pores of the wire cloth will be deformed, and so it is not possible to control the distribution of the openings.

While such a die may withstand higher temperatures as compared to the polymer based die, its manufacturing is associated with a more difficult sintering process, as higher temperatures are required. Moreover, the finished die suffers from the same advantages as that made of polymer material.
